info: reading kernel config from /boot/config-3.16.0-0.bpo.4-amd64 ... gdb, nm and ldd are powerful tools when debugging or trying to do a postmortem on a segfault. The message is printed by show_signal_msg() function in arch/x86/mm/fault.c if the show_unhandled_signals sysctl is set. "error" is not an errno nor a signal number, it's a "page fault error code" -- My copy of Linux/arch/i386/mm/fault.c has the following definition for error_code: bit 0 == 0 means no page found, 1 means protection fault bit 1 == 0 means read, 1 means write

What is a Peruvian Word™? Subtract this from the instruction pointer (ip) and you'll get the offset into the .so of the offending instruction. See: https://github.com/docker/docker/issues/10595">docker: add dockerfile and entrypoint script … This lets us easily spawn one or multiple Docker containers running the current local cjdns code. If you wanted to comment on the question or answer, just use the commenting tool.

Note: under certain circumstances, /etc/cjdns won't be mounted and thus config persistence is broken. We can then use the instruction pointer value from the dmesg output and see if we can understand which symbol it corresponds to.

I ran memtester and cpuburn myself and couldn't find any error either. Better, get a debug-instrumented build, and reproduce the problem under a debugger such as gdb.

The container's cjdroute.conf is persisted at and reused from contrib/cjdns/cjdns[-]. Note: under certain circumstances, /etc/cjdns won't be mounted and thus config persistence is broken. Keep in mind that 4 means that bit 2 is set and no other bits are set. Of course, some knowledge of the instruction set and architecture you are working with is required at this point to understand the disassembly.
